vThis invention relatesto imprimen-rents in the air intake assembly .for e vehicle .mit

An object of this invention is to provide means of ltring the air which is taken from the exe terior ofthe-body of va vehicle in the sta. r-idard ai intake assembly, the improvements residing inthe speciii location of the Vair lters and th :near-is' mounting the air filters at said specific locations. y 1

TAncillary objects and features of importance will become apparent in following the description of the illustrated forni of the invention,

"In the drawings: y v,

'gure l is a perspective viewof a standard air intake assembly showing the location thereof in a vehicle which is partially illustrated and which is shown in phantom; t

Figure 2 is an enlarged sectional View taken substantially on the line 2-2 of Figure 41 and in the direction of the arrows;

Figure 3 is an enlarged sectional View taken on the line 3-3 of Figure 1 and in the direction of the arrows, and;

Figure 4 is a sectional view taken substantially on the line 4-4 of Figure 3 and in the direction of the arrows.

As illustrated in Figure 1 the standard air intake assembly I of the vehicle I2 includes various components among which are the defroster I4, heater unit I6, heated air manifold I8, air ducts and 22, the air duct 22 in this instance being provided with two sections 24 and 26. The air intake assembly shown in Figure 1 is purely conventional and shows that the improved features are adapted to be located in a standard air intake assembly for a vehicle.

:The sections 24 and 26 of the air duct 22 have confronting ends 28 and 30 which are spaced from each other and which are adapted to be connected together by a band 32, this band being preferably formed of two semi-cylindrical sections connected together by a hinge 34 at one pair of ends and releasably held togetherY by a latch 36 at the other pair of ends. This'latch is a pivoted arm which is mounted on one of the sections of the band 3 2, resilient in nature, and provided with a keeper 38 at the end opposite from the pivoted end, the keeper being adapted to engage the stop 40 which is fixed tothe other' of the band sections. A cover plate 42 for ythe junction of the band sections is carried by one of the sections and adapted to overlie a part ofthe outer surface of the other section when the band is disposed on the confronting ends 28 and 30 of the duct sections 24 and 26. The band y32 is rcumfereneach other iin@ordertoaconstitute f vfa, pocket; 66,-;

Attention is now invited primarily to Figure 2 to show the construction and assembly of the second lter 60.. There are two iilters 6I] one being provided at the outer end of the duct section 24 and the other being provided at the outer end of the duct 20 inasmuch as lit is now standard to use two intake ducts in an air intake system or assembly for a vehicle.

As disclosed in Figure 2 the duct section ,24' has an air scoop 62 at its outer end and this airv scoop is normally provided with a filtering screen 64 held fastened to a front vehicle body component or panel 66 by means of screws. The added filter may be held fastened in place in advance of the screen 64 by the same screws which hold the screen in place or additional screws 68 as found desirable. The preferable construction of the filter 66 is a layer 10 of filtering material arranged to abut the screen 64 and a part of the panel 66 on one surface thereof and contacted by a screen 12 on the opposite surface thereof, this screen being provided with a resilient bead 'I4 yaround itsk edges to serve as an antirattle device. The screen 'I2 and the layer of ltering material 16 are adapted to seat upon the ledge 'I6 at the bottom of the grille I8 of the vehicle to partially support it, other support being derived from the bracket 80.

The bracket includes two or more vertical Wire pieces 82 and 84 which are spot-welded'or otherwise rigidly fastened to a crank-shaped wire piece 86 which extends transversely across the screen 12. An angular end portion 88 constitutes a part of the crank-shaped member 86 and has a mounting plate 90 fixed to it by standard means, this mounting plate being provided with apertures to accommodate the screws 68 or the standard screws which are employed to hold the filtering screen 68 in place in alignment with the air scoop B2. The opposite end of the crankf shaped member 86 has a rubber or other equivalent material bumper 9| thereon to contact firmly 'the inner surface of apart of the grille 'I8 or the mounting for the grille so that the bracket is held firmly in place and yet, due to the presence of the rubber bumper 9 I, the bracket will not rattle. l i l y In use filters 60 are attachedas described previously in alignment with the air scoops of the ducts 20 and 22. An additional lter 52 is supplied between the duct sections 24 yand 26 so that various impurities from theiair vwhich is taken into the body of the vehicle may berey moved. By using filters as described, it is not a ldifficult or time consuming operation to 'remove them for replacement or cleaning purposes.

Having `described the` v invention, what is claimed as new is:

1. In a vehicle having a body land grille with a body air intake assembly which includes an' air duct provided with an air scoop and a frontal 'Screen for the air Scoop, an air filter located eX- teriorly of said air scoop and having a rear surface confronting said screen, and means for hold-'- ing said air filter against said screen including a bracket provided with mounting means to fasten to a part of the body of the vehicle and'contact the front surface of said lter, said bracket carried by a. part of the vehicle body lbehind the grille and contacting the front surface of the filter, and-a resilient bumper spacing the bracket from the grille by contacting the grille.

2.'In a vehicle having a body and grille with a bracket provided with mounting means to fasten to a part of the body of the vehicle and contactr thev front surface cf said iilter, said bracket carried by a part of the vehicle body `behind the grille and contacting the front surface of the filter, and a resilient bumper spacing thefbracket from the grille by contacting the grille, the vehicle including a ledge below and in advance of the air scoop, said filter resting on said ledge.
